Radio Communication Best Practices
Radio Check Procedure
- Requesting: "[Your call] radio check"
- Responding: "[Their call] from [your call], you are [signal strength] with [audio quality]"
- Signal Strength: Loud and clear / Readable / Weak / Unreadable
Standard Communication Protocol
- Who you're calling - "[Their call]"
- Who you are - "This is [your call]"
- Your message - Keep it brief and clear
- Request acknowledgment - "Over"
- End transmission - "[Your call] clear/out"

🌲 Mosaic Resource Roads — Safe Road & Radio Use
The following procedures apply to all Mosaic Forest Management Corporation ("Mosaic") managed resource roads. All users must be familiar with these procedures to ensure safe travelling conditions. Any vehicles failing to follow the Mosaic Safe Road & Radio Use Procedures should be reported to the appropriate supervisor for action. The use of seatbelts is always mandatory.
Remember, roads are radio assisted — not radio controlled. Drive accordingly, and always expect the unexpected around every corner!

Radio Frequencies
Use the Mosaic designated haul road frequency for the operating area you are working or travelling in. Verify locally before operations.

All Vehicles
- All road users must be fully licensed with correct endorsements, adequately insured for the vehicle's intended use, and follow all applicable driving legislation.
- All vehicles and drivers must comply with applicable rules, laws and regulations (WorkSafeBC, DOT, National Safety Code, Motor Vehicle Act, etc.) to ensure proper driving, loading, securing, inspection and maintenance of all industrial road users.
- All vehicles must have Mosaic designated haul road frequencies for the operating area. Cell phone use is not permitted on Mosaic resource radio roads — drivers need to pay attention to driving and listen to radio traffic for safety.
- All heavy industrial vehicles have the right-of-way at all times.
- Heavy industrial vehicles have little opportunity to move off the centre of the road grade; yield quickly by pulling into an established clearance after safe passage.
- Light vehicle drivers must be aware of pullouts at all times. Light vehicles always drive on the right side of the road and be ready to pull over as required.
- No stopping on any active haul road within an active work permit or clearance. Do not park where you encroach on or obstruct an active road.
- Check with the local Mosaic office to ensure you have contact information for their designated Prime Contractor in case of issues while travelling (log hauling and other industrial activity) ahead of travel.
Speed & Driving Conditions
- Maximum allowable speed is 65 km/hr (unless otherwise posted). Road and weather conditions may warrant slower speeds; posted speed limits should never be exceeded. Ambulances and emergency services may vary from this limit.
- Drive to conditions: sight lines, dust, or weather-related visibility. Maintain safe distances between vehicles.
- Use your call signs when passing slower vehicles near passes or on corners, using extra caution when visibility is poor (weather, snow plows, blades, graders, etc.).
- Be aware that logging trucks can sweep a wide path when loaded.
- Vehicles must use headlights while travelling on logging roads year round.
- Report all road hazards immediately to the Prime Contractor or Mosaic representative.
Bridges
- All bridges are one lane only. Heavy industrial vehicles have the right of way over light vehicle traffic on bridges. Know where you are and pull over.
- Mosaic bridge inventory is managed to support industrial traffic. When in doubt, ask.
Note: Notify a Mosaic representative prior to walking (point loading) across structures with equipment 35 tonnes or greater, to ensure the structure can safely support the weight.
Radio Use Procedures
Known hazards
- Losing track of your location
- Losing track of other vehicles' locations
- Meeting oncoming vehicles without a radio
- Not following calling procedures
- Unnecessary radio chatter
- Using the wrong frequency
- "Walking over" other calls
- Being distracted (phones, music, passengers)
Calling guidelines
Minimum guidelines are stated below for all traffic. Note that some road headings require more communication — narrow, winding, busy roads may require users to call more frequently. Be safe and consistent when conditions change.
The standard radio call sequence is road name → km → direction → vehicle type (as below, other than logging trucks).
- All heavy industrial vehicles must call when entering a new road heading, and at a minimum frequency of every 2 km loaded or empty, or when resuming along a road after being stopped for an extended period.
- Heavy industrial vehicles use "loaded" when km's are decreasing and "empty" when km's are increasing. For example: "Buckley 6km loaded".
- Heavy industrial vehicles other than log trucks identify themselves. For example: "Buckley 4km loaded gravel truck" or "Chemainus 2km empty grader".
- Low beds (transport trucks) identify themselves when calling. For example, when increasing km's with a machine on deck: "Holt 6km empty low bed, machine on".
- In rare cases log trucks may be loaded while increasing km's; in this event call, for example: "Road name 6km empty trailer down".
- Light vehicles must call when entering a new road heading, and at a minimum frequency of every 5 km, or when resuming after being stopped for an extended period. As above, this may need to increase on busy roads.
- Light vehicle traffic uses "down" when km's are decreasing and "up" when km's are increasing. For example: "Buckley 6km down".
- Some locations have Radio Control Points (RCPs), established for high-risk road sections and marked as RCPs on the signage — these are must-call points.
